El Pegomastax (Pegomastax en la versión original del juego) es una de las criaturas disponibles en ARK: Survival Evolved



This section is intended to be an exact copy of what the survivor Helena Walker, the author of the dossiers, has written. There may be some discrepancies between this text and the in-game creature.


Among the bottom of the island's dinosaur food chain is a small herbivore called Pegomastax fructarator. It is content to spend all day alone, gorging itself on far more food than you might reasonably expect for a creature of its tiny stature. Its beak appears perfectly evolved for collecting food from plants while avoiding the indigestible fibrous strands. Pegomastax is likely to ignore any nearby creature and continue foraging, unless it is attacked. At which point, it turns into a very aggressive (though rather unthreatening) opponent, shrieking and wooping far above its actual threat level. You would expect a creature this small and weak to live in flocks, but Pegomastax seems to be fairly solitary in nature.


While not pretty, and far too small to ride, tribes often keep Pegomastax around as a kind of farming aid. Its skill at scavenging means that it collects an extraordinary quantity of seeds and berries, while also handily gathering the rare Flowers, Mushrooms, and other ingredients necessary to cook up unusual concoctions.


Contrary to the dossier, the Pegomastax is a relatively aggressive animal, attacking survivors on sight. However while its damage is very minimal, the Pegomastax can steal items from a player's inventory; aiming primarily for the items in your last inventory section. If the last inventory section is empty, it will try to steal from other inventory sections. Once tamed, the Pegomastax is a friendly creature that will ride on the player's shoulder.


The Pegomastax is a small herbivorous biped with several avian features. First is its beak, which grants the creature a strong bite to crush nuts and fruits. The beak also has small boar-like tusks in it, serving as a tool for harming attackers, humans or dinosaurs. Second is the feathers that cover its back. Unlike those of birds, they are stiff and stand straight like porcupine's quills, though nowhere near as dangerous.

Color Scheme and Regions[]

This section displays the Pegomastax's natural colors and regions. For demonstration, the regions below are colored red over an albino Pegomastax. The colored squares shown underneath each region's description are the colors that the Pegomastax will randomly spawn with to provide an overall range of its natural color scheme. Hover your cursor over a color to display its name and ID.

This information can be used to alter the Pegomastax's regions by entering cheat SetTargetDinoColor <ColorRegion> <ColorID> in the cheat console. For instance, cheat SetTargetDinoColor 0 6 would color the Pegomastax's "main body" magenta.

Aumento de estadísticas al subir nivel en estado salvaje

Escribe los valores de la criatura salvaje para revisar en que estadísticas sobresale más. Los valores marcados con verde en una criatura de alto nivel son muy buenos para la crianza/reproducción. Si ya has domesticado una criatura, puedes intentar recuperar la información que tenía cuando era salvaje con la siguiente herramienta: ARK Stats Extractor.


Nota: después de que la criatura sea domesticada, conseguirá algunas bonificaciones a sus estadísticas dependiendo de la efectividad del domesticado. Esto dificulta el obtener los niveles precisos de una criatura domesticada, por lo que esta calculadora te ayudará mucho, ya que está pensada para dinosaurios salvajes únicamente. Con ella, podrás tener una idea sobre la distribución de las estadísticas de una criatura.


The Pegomastax has a unique variation to the Passive Taming mechanic - rather than pressing E to feed an item to the creature, you must allow it to Pickpocket the item from you. This deals a minor amount of damage, after which the Pego will run away and there is a delay before it can be "fed" again. It will prioritise the item held in your last inventory slot, but will move on to steal other random items if your last inventory slot is empty - food items stolen from other slots or your inventory will still count toward the tame. If you have no items - it will become conventionally aggressive. Note that Pickpocketing will steal the entire stack, not just an individual item.

Items that the Pegomastax steals can only be reprised from its corpse or its inventory (tamed or knocked out), with the exception of valid taming foods (i.e. those listed in the table below as well as all types of Kibble) that will be lost.

The amount of consumables in a stack appears to improve taming time, but this is not a 1:1 ratio with the below table (Tested: A level 25 took 4 stacks of 100 mejoberries to tame).

Taming Effectiveness is always 100% (i.e. +50% bonus levels) unless damaged, although damaging a passive tame will reset all Taming Affinity (Progress).

Put mejoberries in stacks of 20 in your inventory, only carry berries let him steal a stack at a time, he will lose a little taming before returning to steal again, a small 1 x 1 box works well to keep him from running away too far after stealing each time. If you encounter problems with dropping tame despite continued stealing, try a larger box and giving the Pegomastax more room.

In rare cases a Pegomastax is also tamed directly when hitting them with the primary attack of a dino the first time a Pegomastax attacks.

Comida preferida[]


En esta sección se describe cómo enfrentarte a un Pegomastax.


El Pegomastax atacará en cuanto te vea, robándote un objeto aleatorio de tu inventario cuando lo haga y huyendo con él.


Persíguelo y cázalo para recuperar el objeto que te haya robado. No es difícil de matar, pero se mueve rápidamente, así que ten cuidado o lo perderás de vista.


Podrás usar casi cualquier arma, aunque las armas a distancia son mejores para evitar las dificultades de tener que acercarte a ellos.


El único peligro que representa esta criatura es que te robe un objeto importante mientras estés en mitad de una batalla. De resto, no inflige mucho daño, así que sobrevivirás a él incluso en los niveles más bajos.


El Pegomastax tiene muy poca salud, por lo que podrás acabar con ellos rápidamente cuando los alcances.

Stealing prevention[]

There is a way to prevent, or at least lower, the risks for a Pegomastax stealing an important item from your inventory. It is unknown if it is a bug or if it is intentional because of taming techniques, but a Pegomastax will almost certainly steal the item that is in the rightmost slot of your action bar. That is if there is an item in that slot and you are not holding something in your hands. A simple trick is to bring something somewhat useless and easily stackable that you would not care if the Pegomastax steals it or not, such as spoiled meat. Bring a stack of spoiled meat with you and split it into smaller stacks in your inventory. The more stacks of spoiled meat there are, the more likely the Pegomastax will steal one of those instead of your other stuff. After that, all you have to do is some inventory management to make sure all those stacks of spoiled meat don't annoy you when you want to take something in your inventory. To even lower the chances of a Pegomastax stealing your important stuff, be sure to put one of those small stacks of spoiled meat in the rightmost slot of your action bar. Like mentioned above, the Pegomastax will almost certainly steal the item in that slot instead of stealing something else. Pegomastaxes seem to have a "hierarchy" of pickpocketing. First, they will steal what is in your hands. If you are not holding anything, they will steal what is in the rightmost slot of your action bar. Finally, if there is nothing in that slot, they will steal a random thing from your inventory. So it is recommended to put some spoiled meat in that slot so that a stalky Pegomastax would steal it, thinking it just stole something important for you, while actually you don't care at all about it. After a Pegomastax stole it, just open your inventory and put another one in that slot. If another Pegomastax comes by or if the same returns to steal something else, it will steal the newly placed stack of spoiled meat.



  • Thief: It steals items from players then attempts to run from them (there is also a chance of it taming).
  • Pet: Like the Dimorphodon and the Compy, the Pegomastax can ride on its owner's shoulder. Some survivors tame it merely for an unusual looking pet.
  • Backpack: It can't carry much, but the Pegomastax can be used to hold smaller items to lighten the load when on a player's back.
  • Seed Gatherer: the Pegomastax can be thrown at berry bushes to collect random seeds for farming.
  • Collector:
  • Swarmers


The Pegomastax steals things from another player's inventory. What it steals depends on what is carried by the survivor, particularly in their inventory slots. This can prove useful; for example acquiring a higher grade weapon perhaps to turn the tide on an enemy.

  • Dossier revealed on 18, September, 2015[1]
  • Pegomastax means "strong jaw".
  • These creatures are quite adept at stealing from players and can even take items from players' inventories while those players are mounted on dinosaurs. Great care should be taken to constantly replenish the quick item slot after being robbed as these creatures are common in groups and another is usually lurking around.
  • Although the Dossier mentions that the temperament is Defensive this statement could not be more false. The Pegomastax is extremely aggressive and will attack the player and nearly any tamed creature, even the Rex, without hesitation. It may be important to keep some creatures on neutral to protect passive dinos in your base, just in case a Pegomastax slips in and starts attacking.
  • Pegomastaxes can be very threatening to the player as it can steal many valuable things like Element and even cryopods. If it gets stolen, make sure you don’t lose it or you may lose these valuable items.
  • On ARK: Survival Evolved Mobile the Pegomastax could be found for the first time in the Corrupted Lair of the Thief Dungeon, released on 2/4/2020. It doesn't live on The Island.
  • On ARK: Survival Evolved Mobile you cannot apply Soothing Balm to make it tame faster.
  • On ARK: Survival Evolved Mobile it is the only creature to have a true 100% taming and will tame a level 45 on easy, 225 on medium, 450 on hard, and 675 on brutal.
  • It is one of the most hated creatures in the game for a majority of players due to its habit to steal items and run off with them.
  • The ones found in the ocean biome in Genesis: Part 1 do not attack players or tames unless provoked. While this is helpful in most cases, it is a hindrance in taming it.
